Make a Face
This example shows a simple smiling face built with SVG shapes: a yellow circle for the head, two black circles for eyes, and a curved path for the mouth. The face is centered in a 960 by 500 canvas, with the mouth drawn using an arc from the D3 library, specifically using the `arc()` generator to define an arc with an inner and outer radius. The code uses React to render the SVG elements, and D3 is used for the arc path generation. The rendering approach is purely declarative, with fixed coordinates for all facial features.
